Patent DE-19831247-A1 (DE)
Title: Serpentine pipe configuration for use as chaotic static mixer, heat exchanger or reactor
Inventor: SCHMIDT ULRICH
IPC: B21D11/06
Filed: 1998-07-11
Abstract: Here is a new serpentine static mixer. It may also be used as a heat exchanger or reactor. Each of its (e.g.) pipe(s) has a centre line running along the flow direction. Pipe conformation, forms this centre line into a curve. The curve has a parametric representation as a vector of position, in a system of Cartesian co-ordinates. The independent parametric variable t generates the curve. t ranges from minus- to plus infinity. Other relevant parameters and constants include the modulus of t, a radius of curvature in the range zero to infinity and a spacing parameter in the range zero to infinity. The full parametric representation is claimed explicitly. In general it produces ordered, stacked sets of s-shaped pipe coils, of which the sense of rotation reverses repeatedly. Also claimed is (i) use for mixing, heat exchange or to carry out reactions; (ii) the means of manufacture. This employs a bending jig with cylindrical formers on parallel columns, around which the pipe is curved. The formers include recessed pipe grooves. The jig includes an orbital, similarly-grooved pipe-bending wheel, somewhat reminiscent of that on a plumber's pipe bender. The radius of curvature is that used in the representation, and the groove has a helical pitch of half the spacing parameter, i.e. it is the half turn spacing. Bending around the columns takes place in an alternating pattern. The formers can be rotated on their columns and (iii) the bending jig. The formers are stackable on a column, and may have different pitches, varying the turn spacing.

Title: Bale breaker fiber opening roller
Inventor: HERGETH HUBERT DIPL ING
IPC: D01G9/06
Filed: 1998-09-23
Abstract: To clean the roller (1) of a bale breaker, a sensor (6) system registers clinging matter at the roller for evaluation. The material feed is not interrupted while the roller rotation is reversed for a number of rotations. A separation blade (7,8) is positioned against the normal roller rotating direction.
